RemoteIpAddress 始终为空 [英] RemoteIpAddress is always null

问题描述

var test1 = HttpContext.Features.Get<IHttpConnectionFeature>();
var test2 = HttpContext.Connection.RemoteIpAddress;

在 IISExpress 上本地运行应用程序时，这两行正确返回值 0:0:1.

When running the application locally on IISExpress, these two lines correctly return the value 0:0:1.

当我在 IIS 7.5(在 VM 上运行)上发布应用程序时.RemoteIpAddress 总是 null

When I publish the application on IIS 7.5 (which is running on a VM). RemoteIpAddress is always null

我正在使用 ASP.Net 5 RC 1.

推荐答案

您所看到的是准确的，如果没有用的话.IIS 的连接终止，然后转发到 Kestrel，即 v.next Web 服务器，因此与 Web 服务器的连接确实来自 localhost.

What you're seeing is accurate, if not useful. Connections termination at IIS, which then forwards to Kestrel, the v.next web server, so connections to the web server are indeed from localhost.

您需要做的是启用对 X-Forwarded-For 的支持

What you need to do is enable support for X-Forwarded-For

1. 添加Microsoft.AspNet.HttpOverrides 包

2. 在你的 Configure() 方法中添加

    app.UseOverrideHeaders(new OverrideHeaderMiddlewareOptions
    {
        ForwardedOptions = ForwardedHeaders.XForwardedFor | 
                           ForwardedHeaders.XForwardedProto
    });

请注意，此包将在 RC2 中更改以使其使用更安全.

Note that this package will change in RC2 to make it safer to use.
